Valence Electrons and Their Role in the Periodic Table

This video tutorial from Moomoomath and Science explains valence electrons and how to use the periodic table to illustrate and diagram them. It covers the basic structure of atoms, including protons, neutrons, and electrons, and how electrons are arranged in shells around the nucleus. The video provides demonstrations using carbon and sulfur to show how to determine electron configurations and valence electrons. It also introduces the Lewis dot structure as a method to represent valence electrons. The tutorial concludes with a call to action to subscribe for more educational content.
